Running pytest through CLI with pytest-xdist runs fine (pytest -n 3 {test}). When running the same set up in PyCharm I get Context version conflict, stating that I need to lower my pytest version. When I lower the version to below 4, pycharm is able to run the pytest script through the pytest runner.
Here is the requirements.txt:
apipkg==1.5
atomicwrites==1.3.0
attrs==19.1.0
execnet==1.5.0
more-itertools==6.0.0
pluggy==0.9.0

selenium==3.141.0
six==1.12.0
urllib3==1.24.1
and the error:

I want to be able to run the same setup in pycharm as I do from CLI
Solved the issue: PyCharm had pytest-fixture-config installed. I had to remove the package and running my tests worked. pytest-fixture-config states Pinned pytest<4.0.0 until all deprecation warnings are fixed.

It looks like related to Cython in spicy package? Does anyone got this error.
Thank you guy for helping me.
I fixed this problem.
The reason is my pip3 version was too old (v.9).
So I updated it to the newest version, it work like charm.
sudo python3 -m pip install -U pip

I have tried downgrading pip from (18.1 to 9.0.1) and also downgrading pipenv, it did not resolve the issue.
This stupid policy keeps telling to add more details, hence everything after this is only a filler.
I was so happy to publish my first package in pypa but then this stupid issue happened. I have wasted a lot of time already.
Manged to fix the issue temporarily by downgrading virtualenv -
pip install virtualenv==15.* --upgrade
I'm a Mac user, and I frequently face frustrations when installing python packages.
This time, pipenv seems not working properly.
I successfully installed pipenv.
$pipenv --version
pipenv, version 11.10.1
However, When I try to init pipenv shell, I got error like this:

I searched some workarounds that worked for other people but they're for oter packages and didn't work for me. Thanks for any help.
Looks like you are missing CFFI, which also has a couple of dependencies. According to this you need to install a couple of dependencies, probably python-dev and libffi-dev.
I want put my working app on Heroku. The application using Django and chat based on Twisted websockets. I don't know it's good approach but I installed twisted via heroku bash, but when i want to run my chatserver.py I have an exception because some Twisted module requires OpenSSL which is not installed on my env.
So simply question, how to install Twisted to work with websocket on Heroku?
Update
when I run twistd -n -y chatserver.py:
